Marco Rubio Campaigns In New Hampshire On Primary Day

MANCHESTER, NH - FEBRUARY 09: Volunteers and staff for Republican presidential candidate Sen. Marco Rubio (R-FL) with trackers and demonstrators, including Kevin McAlister of the American Bridge 21st Century political action committee dressed as a robot, pushed, shoved and wrestled as Rubio stopped to thank supporters outside the polling place at Webster School February 9, 2016 in Manchester, New Hampshire. With a good showing in the Iowa caucuses, Rubio has stepped into the crosshairs of fellow Republicans running for president and super PACs that want to slow his momentum with attacks on what they call his robotic and repetative messaging.
